13 Piece Multi-Purpose Drill Bit Set

Very expensive drill bits. They produce a lot of vibration and the shanks are long and flexible, causing a number of problems. The hole diameter is not going to be decimal accurate. The vibration will cause brittle material to chip, crack, or blow out. This is not a set of drill bit I would recommend for any detail work or project. I would like to send them back because they are not worth $190.00 with any type of lifetime warranty. There are a lot of choices out there with cobalt, titanium, and carbide mixtures that are much better at drilling holes. Just sharpen them or buy a new. You can get a lot of replacement bits for $190.00. I would sell my for half price. Had high hopes for them but reality is a scientific fact.

This company you can order something but they will not help you return it when it does not work out. You have to pay to send it back. Worst drill bit ever, could not drill thought a piece of metal.

Very fast delivery
